摘  要:
为降低荔枝酒中挥发酸含量,以同时利用可发酵性糖和乙酸的酿酒酵母为出发菌株,研究丙酮酸转运抑制剂对酿酒酵母代谢醋酸的影响。结果表明:在荔枝酒酿造过程中,添加0.5~0.75mmol/L的α-氰基-4-羟基肉桂酸(α-CCA)对酿酒酵母代谢醋酸具有显著影响,促使酿酒酵母表达较高的乙醇脱氢酶(ADH)、乙酰辅酶A合成酶(ACS)、异柠檬酸裂解酶(ICL)和苹果酸合成酶(MS)的酶活性,提高酿酒酵母代谢醋酸的能力。添加0.5mmol/L的α-CCA,酿酒酵母代谢醋酸的量比对照提高150mg/L。

摘  要:
In order to reduce the acetic acid in lychee wine,S.cerevisiae,which could simultaneously use the fermentative sugar and acetic acid as its carbon resources,was used to investigate the effects of supplemented withα-Cyano-4-hydroxycinnamic acid(α-CCA)on acetic metabolism during lychee wine fermentation.The results indicated that supplemented with 0.5-0.75mmol/L ofα-CCA had significantly influenced the acetic acid metabolism,since higher enzymatic activity of ADH,ACS,ICL and MS were expressed.When supplemented with 0.5mmol/L ofα-CCA,compared with control,the amount of acetic acid metabolized was increased by 150mg/L.
